SARA-U2 - HSPA modules with 2G fallback

The world's smallest global HSPA/GSM module

SARA-U2 UMTS/HSPA modules provide efficient and cost effective high-speed mobile connectivity in an ultra-small LGA form factor. The SARA-U2 series offers seamless drop-in migration from GSM (SARA-G3 modules) and CDMA (LISA-C modules) as well as easy migration to LTE (TOBY-L / TOBY-R / LARA-R)modules).

SARA-U2 modules feature HSPA data-rates of 7.2 Mb/s (downlink) and 5.76 Mb/s (uplink). The modules have an extended operating temperature range of -40 to +85°C, low power consumption, and a rich feature set including dual stack IPv4 / IPv6.

The SARA-U2 series is ideal for a wide range of industrial and consumer applications, such as connected navigation systems, mobile-internet devices, security and surveillance systems, eCall, fleet management, metering, anti-theft systems, and other automotive applications.

SARA-U2 modules provide a fully integrated interface to u-blox satellite positioning chips and modules to support telematics applications.

The SARA-U2 series includes variants supporting a combination of global bands and band combinations for North America and Europe/Africa/Asia. There is also a cost-saving UMTS-only variant for North America.

An extensive set of national regulatory and operator certificates is available. RIL software for Android and Embedded Windows is available free of charge.

EVK-U27 Evaluation Kit for SARA-U270

u‑blox EVK‑U2x evaluation kits provide simple, flexible and ready‑to‑use environments for evaluating u‑blox' LISA‑U and SARA‑U series W‑CDMA cellular modules, as well as for designing and testing cellular and GNSS applications. The kits are user‑friendly, and have both USB and RS232 interfaces for development, testing and tracing. The kits come with a built‑in u‑blox GNSS receiver module, giving designers the flexibility to either test GSM/GPRS functionality alone or to integrate it with u‑blox GNSS technology.

For evaluating Assisted‑GNSS (A‑GNSS), a u‑blox AssistNow A‑GNSS client is embedded in the firmware stack, providing users with the option of integrating and testing our license‑free A‑GNSS solutions. The kits are to be used with a Windows PC via USB interface, and require an activated SIM card (not included). USB drivers can be downloaded from u‑blox website.


Kit includes:

  • Evaluation board with LISA‑U2 or SARA‑U W‑CDMA module and u‑blox GNSS module
  • USB cable
  • Cellular (UMTS/GSM) antenna
  • GNSS antenna
  • Power adapter
  • Audio headset
  • Quick start card
